SEALED ENCLOSURE APPLICATIONS
CompVT woofers perform well in any size sealed enclosure between the minimum and maximum
volume recommendations. These systems will exhibit benefi ts of both designs: Minimum produces
high-impact bass, and maximum generates low bass frequency protraction. Overall, the system will
sound more like the recommended enclosure design it is closest to in enclosure volume. These
enclosure recommendations have been calculated with the airspace inside the enclosure and include the
displacement of the woofer. All sealed-enclosure airspace should be fi lled to 50% loose poly-fi l (polyester
fi berfi ll) stuffi ng.
Do not make the airspace greater than the maximum enclosure volume recommendation.
To make the most effi cient use of space when building the Sealed Minimum enclosure for your CompVT
subwoofer, you must use the included clearance plate. The clearance plate allows the CompVT
subwoofer to sit recessed within the back panel of the subwoofer box to minimize the enclosure’s
depth. The clearance plate must seal tightly. First, use a plunging router, straight-cut bit, and a circle jig
to create a 1/16” (2mm) deep recess with an outer diameter of 6 1/2” (16.7cm) and an inner diameter
of approximately 5” (12.7cm). Center the recess behind the subwoofer on the back panel. Then, cut
a 5 1/4” (13.3cm) diameter hole in the center of the recess all the way through the back panel. Using
the clearance plate as a reference, drill the six screw holes with a #29 (0.136”, 3.5mm) drill bit. Next,
countersink each screw hole using a 1/4” (6mm) drill or countersinking bit so the clearance plate will fi t
tightly against the back panel. Remove the paper backing from the foam gasket and adhere it to the inside
of the clearance plate. Then, fasten the clearance plate to the box with six #8 screws. See
